dryriver writes with this excerpt from the BBC about the latest device from Makerbot: "A desktop device that can quickly scan objects so they can be replicated using a 3D printer has gone on sale. The Makerbot Digitizer, which costs $1,400 (£900), will be shipped to the first buyers in October. Demand for the machine appeared to overload the company's store when it went on sale on Thursday evening. The Digitizer is the latest product looking to bring 3D printing to mainstream technology users — but experts are sceptical. The machine is designed to allow the replication of objects without any need for the user to learn any 3D modelling software or have any other special expertise. The time it takes to scan an object varies, but one demonstration involving a small gnome was said to take around 12 minutes. "The MakerBot Digitizer is for early adopters, experimenters, and visionaries who want to be pioneers in Desktop 3D Scanning," the company says. "This includes, but is not limited to, architects, designers, creative hobbyists, educators, and artists.""

The current nightly builds have been released for the Google Galaxy Nexus, HTC One, Samsung Galaxy S4, Samsung Galaxy S3, LG Optimus G, Sony Xperia Z, and Motorola Razr among others. As always, CyanogenMod team reminds that these are experimental."

Zothecula writes "A team at the Harvard School of Engineering and Applied Sciences (SEAS) has come up with a promising new way to create 3D images from a stationary camera or microscope with a single lens. Rather than expensive hardware, the technique uses a mathematical model to generate images with depth and could find use in a wide range of applications, from creating more compelling microscopy imaging to a more immersive experience in movie theaters."

Zothecula writes "The additive layer process of conventional 3D printers means they are usually limited to bottom up fabrication on three axes. Now, the LA-based NSTRMNT team has created a 3D printing process called suspended disposition that gets around gravity by printing objects within a gel. Not only does this allow freeform additive fabrication on six axes, it also enables an 'undo' function."

Via Engadget comes the news that Google's latest (and quickly sold-out) toy, the Chromecast, may soon be hacked out of one-trick-pony status; just a few days after it came out, the folks at GTV Hacker have successfully turned their attention to the Chromecast, and managed to exploit the device's bootloader and spawn a root shell. Some interesting findings, as explained in their blog post: "[I]t’s actually a modified Google TV release, but with all of the Bionic / Dalvik stripped out and replaced with a single binary for Chromecast. Since the Marvell DE3005 SOC running this is a single core variant of the 88DE3100, most of the Google TV code was reused. So, although it’s not going to let you install an APK or anything, its origins: the bootloader, kernel, init scripts, binaries, are all from the Google TV. We are not ruling out the ability for this to become a Google TV 'stick.'"

A few days ago, the CyanogenMod teamed teased a new project named Nemesis, a series of planned improvements to the user interface. An anonymous reader writes with news of the first part: a new camera application designed to replace the neglected stock Android camera app. From the article: "As cameras and camera software becomes an increasingly important part of our mobile experience, a great photography experience on your smartphone can make all the difference. The CyanogenMod project has decided to take smartphone photography a lot more seriously with the release of Focal, and all new camera app for CM users everywhere." Android Police also has an early look with screenshots. The menu system in particular looks a lot nicer to use than the current cumbersome interface to white balance/exposure/scene settings. Focal should be merged into nightly releases soon.

Travis Goodspeed has authored a blog post detailing his method of tracking low-earth-orbit satellites. Starting with an old Felcom 82B dish made for use on maritime vessels, he added motors to move it around and a webcam-based homemade calibration system. "For handling the radio input and controlling the motors, I have a BeagleBone wired into a USB hub. These are all mounted on the trunk of the assembly inside of the radome, sending data back to a server indoors. ... In order to operate the dish, I wanted both a flashy GUI and concise scripting, but scripting was the higher priority. Toward that end, I constructed the software as a series of daemons that communicate through a PostgreSQL database on a server inside the house. For example, I can run SELECT * FROM sats WHERE el>0 to select the names and positions of all currently tracked satellites that are above the horizon. To begin tracking the International Space Station if it is in view, I run UPDATE target SET name='ISS';. For predicting satellite locations, I wrote a quick daemon using PyEphem that fetches satellite catalog data from CelesTrak. These positions are held in a database, with duplicates filtered out and positions constantly updated. PyEphem is sophisticated enough to predict in any number of formats, so it's easy to track many of the brighter stars as well as planets and deep-space probes, such as Voyagers 1 and 2."

hypnosec writes "Adapteva has started shipping its $99 Parallella parallel processing single-board supercomputer to initial Kickstarter backers. Parallella is powered by Adapteva's 16-core and 64-core Epiphany multicore processors that are meant for parallel computing unlike other commercial off-the-shelf (COTS) devices like Raspberry Pi that don't support parallel computing natively. The first model to be shipped has the following specifications: a Zynq-7020 dual-core ARM A9 CPU complemented with Epiphany Multicore Accelerator (16 or 64 cores), 1GB RAM, MicroSD Card, two USB 2.0 ports, optional four expansion connectors, Ethernet, and an HDMI port." They are also releasing documentation, examples, and an SDK (brief overview, it's Free Software too). And the device runs GNU/Linux for the non-parallel parts (Ubuntu is the suggested distribution).

An anonymous reader writes "A new study by researchers in the Built Environment Research Group at the Illinois Institute of Technology shows that commercially available desktop 3D printers can have substantial emissions of potentially harmful nanosized particles in indoor air. Many desktop 3D printers rely on a process where a thermoplastic feedstock is heated, extruded through a small nozzle, and deposited onto a surface to build 3D objects. Similar processes have been shown to have significant aerosol emissions in other studies using a range of plastic feedstocks, but mostly in industrial environments. In this study, researchers measured ultrafine particle concentrations resulting from a popular commercially available desktop 3D printer using two different plastic feedstocks inside an office. Ultrafine particles (or UFPs) are small, nanosized particles less than 100 nanometers in diameter. Inhalation of UFPs may be important from a health perspective because they deposit efficiently in the lung and can even translocate to the brain. Estimates of emission rates of total UFPs in this study were high, ranging from about 20 billion particles per minute for a 3D printer utilizing a lower temperature polylactic acid (PLA) feedstock to about 200 billion particles per minute for the same type of 3D printer utilizing a higher temperature acrylonitrile butadiene styrene (ABS) feedstock. The emission rates were similar to those measured in previous studies of several other devices and indoor activities, including cooking on a gas or electric stove, burning scented candles, operating laser printers, or even burning a cigarette."

DeviceGuru writes "WigWag has developed a home automation kit that combines a Linux-based 6LoWPAN router with sensor units running the open-source Contiki IoT (Internet of Things) OS. Users can add ZigBee, Bluetooth, and other modules to expand the home network, and the WigWam development kit provides shield development boards for use with Arduino and Raspberry Pi SBCs. Users control the devices with a smartphone app (initially Android-based) and associated WigWag cloud service, which lets the devices remotely respond to sensor-based events such as motion detection, rain, noise, etc. Developers can create rules-based scripts for controlling devices using WigWag's open-source Javascript-based DeviceJS development environment. WigWag used a Kickstarter page to fund production and has already tripled its goal."

super_rancid writes "In a 7,000 word interview with Raspberry Pi's founder posted on TuxRadar.com, Eben Upton talks about the challenges of managing such a successful project, what may be in the Raspberry Pi mark 2, and why he wishes he'd backed the Parallela Kickstarter." On interesting answer: "We were thinking of booting into Python or booting into Scratch. For younger kids, boot into Scratch. Have an environment where it’s Linux underneath, boots into Scratch and hold down a key at a particular point during boot and it doesn’t boot into Scratch it just drops into the prompt. So you can play with Scratch for six months, once you’re happy with Scratch you turn over the page and 'Hold down F1 during boot,' and it’s like 'Oh look - it’s a PC!' So I think that’s something we’d really like to do."

New submitter Anita Hunt (lissnup) writes "This snooping hack-in-a-backpack could become a hot Summer accessory, since Reuters reported that 'researchers at iSec hacked into a Verizon network extender, which anyone can buy online, and turned it into a cell phone tower (video interview) small enough to fit inside a backpack capable of capturing and intercepting all calls, text messages and data sent by mobile devices within range.'"

colinneagle writes "At the Inside 3D Printing conference in Chicago, Microsoft senior product manager Jesse McGatha discussed why Microsoft recently announced that Windows 8.1 will support 3D printing, even giving a demo of a sample app for printing a design file. But in the presentation it became clear that Microsoft is capitalizing on the recent hype of 3D printing and positioning itself to capitalize on the future consumer markets for 3D printing. However, a Gartner analyst recently warned that 3D printing may not become the household consumer item that some are making it out to be. So, by capitalizing on the buzz, Microsoft may attract makers, innovators, and even enterprise customers that use 3D printing, but avoids any risk if the consumer market fails to reach its potential."

An anonymous reader writes "Last October, we discussed Andrew 'bunnie' Huang's effort to build a complete open hardware laptop, called the Novena. bunnie has now posted a progress report on the laptop's design and construction, showing the latest revision of the board, the display, and a hack to use it as a secure router. bunnie says, 'At the end of the day, we're having fun building the laptop we always wanted — it's now somewhere between a python-scriptable oscilloscope, logic analyzer, and a laptop. I think it will be an indispensable tool for hacking, particularly for doing signal analysis which requires coordination across multiple protocol layers, complex trigger conditions and/or feedback stimulus loops. As for the inevitable question about if these will be sold, and for how muchonce we're done building the system (and, "done" is a moving target — really, the whole idea is this is continuously under development and improving) I'll make it available to qualified buyers. Because it's open-source and a bit quirky, I'm shy on the idea of just selling it to anyone who comes along wanting a laptop. I'm worried about buyers who don't understand that "open" also means a bit of DIY hacking to get things working, and that things are continuously under development."

An anonymous reader writes "South African Quentin Harley has picked up the $20,000 Gada Uplift prize for making the open source RepRap 3D printer design easier to build, cheaper to construct, and — most importantly — capable of printing more of its own parts. Lots of background on Harley and his RepRap Morgan are available on his website." A further goal of the RepRap Morgan project is to replace the Prusa Mendel as the default RepRap model. And they are on track to hit less than $100 in parts, excluding the printing bed. You can grab the hardware design and the controller firmware over at Github.

RockDoctor writes "After spending several years on supporting the uptake of 3-D TV, the BBC has accepted that people don't want it, and are turning off their 3-D channels following an uptake of under 5% of households with 3-D equipment. I can just feel the joy at not having wasted my money on this technology."

GenieGenieGenie writes "After all the talk of printed guns and the problems they pose to traditional methods of perimeter security, we get a live demo courtesy of some rather brave journalists from Israel's Channel 10, who took the plastic weapon known as the Liberator past security into the Israeli parliament, and held it within meters of the Israeli prime minister Benjamin Netanyahu. I say brave because had they been caught pulling this stunt, which involved taking their toy out of the bag while sitting in the audience of a speech by the prime minister, they would have faced some real steel. Haaretz has the video (sorry, Hebrew only at the moment) [Google-translated version of the article -- Ed.] where you can follow the breach (from ~6:30) and see them pass the metal detector and the moment when the gun comes out. The movie also shows some testing of the gun in a police-supervised weapons range. Parliament security officials said that 'this is a new phenomenon and they are checking the subject to give it a professional solution as quickly as possible.' I hope this doesn't mean we will now officially face an era of ever more intruding security checks at entrances to events like this." Would-be Liberator printers, take note: the testing shows the barrel violently separating from the rest of the gun.

snydeq writes "Open centers of grassroots innovation, hackerspaces offer opportunities to source talent, create goodwill, and push technology forward, writes Open Software Integrators' Phil Rhodes. 'I had the good fortune to be able to attend Maker Faire North Carolina this weekend in Raleigh, N.C. ... At this local Maker Faire, I was struck by the number of hackerspaces represented. The energy, buzz, and activity around their booths was captivating,' Rhodes writes. 'Amid all this buzz, it dawned on me that everyone should be excited about hackerspaces and what they represent, both for their local communities and the world. Although the hackerspace movement is growing rapidly, many people are still not familiar with them, where they are located, or what they do. So let's examine the hackerspace world and explore why you should give a crap about it.'"

An anonymous reader writes "A few weeks ago, Slashdot featured a cheap platform performing 80FFTs per second to recognize whistles. The platform is open hardware/open source and is aimed for sound processing projects. To this goal, the creator (limpkin) just implemented a simple proof of concept algorithm that will control your lighting once the platform listens to a particular word. A small video has been made to explain the basic concepts of sound recognition to encourage hobbyist to make their own."
